Just wondering how you guys split up power. Do you use one big battery or perhaps 1 big and 1 small? Do you have a master switch that turns everything on, or do you just plug your lipos in when ready? If you use 1 battery for flight computer/ webcam, how big is it? Do you make your own distruibution, or buy something? I'm thinking 1 battery for flight computer/ webcam will be nice, clean power.
